"how about special version of WS-10 specially developed for J-20 with short life span increase thrust 34000 -35000 lbs, there are rumours on numerous site and forums that J-20 is using special version of WS-10 called WS-10G"
Internet rumors mean nothing.
Show me official reports or pictures, that there is a
WS-10G, that looks like the current J-20 engine, then we talk.
This is the WS-10B, with reported 14 tons thrust, on this display. There is nothing similar to the current J-20 engine.
NOTHING.
Show me, where is the similarity.

"use common sense, bro. WS-10 is a major turbofan of China, and its already matured"
The
WS-10 was completed in
2006 and started production, then numerous problems was discovered, around 2009, when installed in J-10 and J-11, and the whole fleet was grounded. And all the engines, have to be returned, to the factory, for repairs.
That can't be evidences that WS-10 is a mature product. In fact, this is the episode that makes people doubt, whether China has the technology and experiences, to produce WS-15 for J-20, or any turbofan engine, at all.
This Chinese report says the
WS-10B was completed in
2015 and started production. That's 4 years, after J-20 first flown.

The project to produce a TWR>10 engine was initiated in the 1980's, around the same time as WS-10. The WS-15 engine core, passed all tests on
2005, and the WS-15 was officially started on
2006. Development of the whole WS-10 engine, with TWR >8, was completed on
2006. This is not too far apart.
"
last hear I was listening to that news ground testing of WS-15 was completed and started air to testing on IL-76 engine testbed from the all senior Chinese members like @cirr, @ Chinese Tiger 1986 , @Beast, @wangklon, @clnieo and others here on PDF "
"senior" PDF member, or not, it means nothing.
This is an internet forum, not the Liming Engine Factory of China, that produces the WS-10 and WS-15 engine.
Mr. Deino is a Moderator here. He has written several books on Chinese Combat Aircraft. He is a noted international authority on this subject. He has contributed numerous articles to various international aviation magazines. I have read some of them. He is a senior member of several internet defense forums. I don't think anybody else has put this much time and effort into study Chinese Combat Aircrafts than him, in this forum.
Mr. Deino has insisted, that J-20 is currently using, a version of the
AL-31-F engine, not the WS-10 or WS-15.
Do you think he is right?
